From our commit CI

This pull request has 2 commits.
Please squash them into a single commit before merging.
You can use git rebase -i HEAD~N
...where N is the number of commits you want to squash together. The PR check conveniently tells you this number! For example, if the check says you have 3 commits, you would run: git rebase -i HEAD~3.
Because you have rewritten the commit history, you must use the --force flag to update the pull request: git push --force

Please run the commands above to squash to 1 commit please! (this helps keep our git history cleaner when using Copybara which lacks squash commit functionality)

Thank you @dantelmomsft. When merging this I actually noticed that there's a slight mismatch in the internal formatter vs the java plugin (internal formatted one of the strings in the test!). I'll be updating the CI to not block external contributions for this in the future and for this PR I'm submitting a manual format fix (#259) so this PR should be auto-merged today when that fix gets in. Sorry for the churn on this!

[Poggecci]

Strange that Copybara committed this but left the PR open...
